Can battery energy storage be used in grid peak and frequency regulation?

To explore the application potential of energy storage and promote its integrated application promotion in the power grid, this paper studies the comprehensive application and configuration mode of battery energy storage systems (BESS) in grid peak and frequency regulation.

Do gas-fired power plants participate in peak regulation?

However, two problems are confronted by gas-fired power plants when participating in the peak regulation of the power system. Firstly, there are problems within the capacity mechanisms and peak regulation ability of gas-fired power plants.

What is the peak regulation principle of LNG?

The peak regulation principle of LNG is similar to that of the underground gas storage. However, LNG facilities are located on the ground, and a fixed location is not required [ 93 ]. Thereby, a suitable site can be chosen by LNG suppliers according to their own preference.

What is peak regulation?

Peak regulation is one of the means to solve such power imbalance issues in peak periods, and it refers to the process that the extra power generation units are required to be put into operation except for the normal generators to meet the power balance [ 5 ].

Are battery energy storage systems a practical and flexible resource?

More flexible resources are needed to supplement and complement regulation to maintain the safe and stable operation of the grid . Battery energy storage systems (BESS), as a practical and flexible regulation resource , have been widely studied and applied for the characteristics of energy time-shifting and power fast-accurate response .

How do thermal generation units participate in peak regulation?

At present, in the process of thermal generation units (TGUs) participating in peak regulation, TGUs change their output in order to track load changes in the power system, which are one of the most common methods used in peak regulation [ 6 ].
